FLUID-DISCHARGE VALVE.

SPECIFICATION formingpart of Letters Patent No. 656,262, dated August 21, 1900. Application filed December 28, 1899. Serial No. 741,880. (No model.)

To LZZ whom, it may concern:

Be it known that we, IRA D. PERRY and JOHN B. WEIR, citizens of the United States of America, andresidents of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Fluid-Discharge Valves, of which the'following is a specification.

Our invention relates to that kind of apparatus or devices used to cut off or control water or other fluid under pressure, and more particularly to that kind in which the fluid is discharged into free space, such as faucets, bibs, stand-pipes, and the like. In this class of apparatus Water or other Huid under pressure is controlled and held in check by means of avalve. This valve is opened and closed usually by means of a stem or spindle connected with the valve and extended to a point beyond the casing, so that a handheld secured to the end of the stem may be grasped to operate the valve. In cocks, faucets, and the like, in Which the discharge-channel eX- tends substantially at right angles away from the stem, the Water tends to travel in the direction of the stem, and 'it is necessary to provide a deflecting -partition, which the stream encounters', thereby directing the greater portion of the water into the discharge-channel. A portion, however, of the Water passes th rough this partition about the stem at the point where the stem passes through the partition and tends to escape or leak through the casing at the point where the stem passes through the casing. To prevent this leakage, the stem is packed, and as the packing wears out and is otherwise objectionable effort has been made to overcome the leakage by special diaphragms and supplemental partitions. In bib cocks or faucets the deflecting-partition is unnecessary, as the water flows directly when the valve is opened toward or through the discharge-chan-l nel; but in these devices the water tends to leak out about the stem, requiring packing.

The object of our invention is lto provide in apparatus of this character means to completely prevent the Water under pressure from traveling along orvabout the stem in such a direction as to escape or leak through the casing and which means shall direct the water completely to and through the discharge-opening and to accomplish this result by the most simple and economical construction.A

Reference may now be had to the accompanying drawings, in which-- Figure l is a vertical central section through one of ourimproved faucets. Fig. 2 is a crosssection on the line @c a; of Fig. l. Fig. 3 is a 6o detailed view of a portion of the faucet, showing a slightly-changed position of the step from that shown in Fig. 1. Fig. 4 is a section on the line y y of Fig. 3. Fig. 5 is a like View of a modified form, showinga lip or extension forming a step. Fig. 6 illustrates still another form of step. Fig. 7 is a cross-section on the line z .e of Fig. 6. Fig. 8 is a view similarto Fig. 6, showing the step formed in the rear of the stem. Fig. 9 is a view similar to Fig. 1, 7o showing the deflector acting to direct the Water into the discharge-channel directly Without lateral deflection, said deflector being so formed as to provide a step Aatthe stem. Fig. 10 is a detailed View similar to 75 Fig. 3, showing a construction to laterally deflect the water and then direct it downward, and thus deliver the Water into the discharge-channel. Fig. 11 is a central sectional view showing our invention applied to 8o a bib-cock.

In carrying out our invention we provide such a construction and arrangement of parts .that the Water or other fluid under pressure cannot travel along or about the stem and es- 8 5 cape between the casing and the stem, for, in effect, the tendency to so travel and escape existing in present forms is counteracted in our device, and whereas in the former some of the water tends to and does travel in the 9o direction of escape in and by our invention the tendency ofthe stream as a whole is to or through the ldiscl:iargechannel. In other words, in our invention the Water is prevented from following along the stem to a point of escape between the casing and the stem and is all directed immediately into the dischargechannel.

The casing is designated at A, forming the delivery-channel B, and the discharge-chanroo nel at D. A valve E controls the fluid-supply from the pressure-pipe H. Astem or spindie J, secured to the valve, extends through the deliector K, the partition L, and through the cap M, a chamber N being formed above the partition L. The stem is operated mannally to open the valve by the handle O, and a spring I returns the valve to its seat. A step a is formed at the stein J.

The operation of our improved faucet is as follows: lVhen the valve E is opened, the water rushes into the delivery-channel B, and it tends to pass directly upward. The shape of the deector K, which,with the casing A, forms the delivery-channel B, diverts or directs the stream of water laterally away from the stem; but as the delivery-channel beyond the deflcctor turns about the water is directed toward and beyond the stein into the discharge-channel D and from thence delivered into free space. Some slight portion of water passes through the detlector K about the stem J and then meets the stream of water delivered to the dischargechannel and is taken into the main body 'of water. As the water rushes past the stem it also moves past the step and by its velocity creates a vacuum and consequent suction in and about the stem, thereby preventing any part of vthe water t rom passing about the stem upward into the chamber N to escape or leak out between the stemv and casin g and causing all of the water to pass into and through the discharge-channel. The presence of the step, notch, orjog a at the stein causes all of the water to shoot into the discharge-channel, as the vacuum is formed just beyond the step and between the top level of the stream of water and the partition L. It is thus apparent that the step at the stem prevents the water from passing up about the stem to escape, and it is one of the essential features of our invention that the step be positioned in close or immediate proximity to the stem and in such close proximity as to create a suction directly about the stem, thereby preventing the passage ot' the water upward about the stem. The step, gradually originating in the rear of the stem and abruptly terminating in immediate proximity to the stem, accomplishes this result.

In Figs. 3 and 4 we have shown the step a a very slight distance in advance of the stein, but still in immediate proximity thereto.

In Fig. 5 we have also shown the partition cut away at b to form the step, which is just beyond the stem.

In Figs. 6 and 7 we have shown a construction involving a double step a and a2.

In Fig. S the step is just in the rear of the stem.

In Fig. 9 we have illustrated a modification in which the gooseneck form of supply-channel B is omitted and the step d is still retained to operate in the same manner and accomplish the same result as previously described.

In Fig. 10 we have shown still another form in which the step (t is formed by the partition L and the top of the supply-channel B.

Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent, is-

l. Means for controlling the closure of Huidvalves comprising a valve, a supply-channel, a discharge-channel, a stem and a step gradually originating in rear of the stem and terminating abruptly in immediate proximity thereto, so as to create a suction directly about the stem.

2. In a cock or faucet, a supply-pipe, a discharge-pipe, a valve and a spindle therefor, extending through or into the discharge-pipe transversely to the direction of the discharge, said discharge-pipe being of increased diameter relatively to the supply-pipe together with a lip or step formed by said increased diameter, in immediate proximity to the spindle.

3. In a cock or faucet, a supply-pipe and a valve therein, a stem for said Valve, said supply-pipe being so shaped as to direct the ow of water awa-y from the spindle, and then transversely across the spindle and a step in immediate proximity to the spindle whereby a suction is created about the stem and the discharge directed past the said spindle.

4. In a cock or faucet, a supply-pipe and a valve therein, said supply-pipe extending in gooseneck form from the valve, away from the spindle and then back transversely across the spindle.

5. In a cock or faucet, a supply-pipe and a valve therein, said supply-pipe extending in gooseneck form from the valve, away from the spindle and then back transversely across the spindle together with a step in im mediate proximity to the spindle.

6. In a cock or faucet, a supply-pipe and a discharge-pipe, a valve, and a valve-spindle extending transversely into or across the discharge-pipe, and a step arranged on the pressure side of the spindle, to direct the iiow of liquid away from the opening in the spindlecasing.
